Silvermex Resources Ltd. ("Silvermex") (TSX VENTURE: SMR) announces
the latest results of its surface trenching program on its optioned
San Marcial Property in southern Sinaloa, Mexico. This successful
trenching program provided numerous high grade results, 18 of the
samples assayed over 300 g/t silver. Highlights include 520.9 g/t
silver across 9.70 meters and 1,770 g/t silver over 1.75 meters.
The results confirm that the high grade silver mineralization
occurs over significant widths and over the entire strike length of
the structure that has been delineated. President Michael Callahan
reports; "This was a very positive step in our 2010 program to
advance the San Marcial project. These results are very exciting as
they replicate the high grades we have seen in past drilling
programs over the entire strike length of the known zone".
The spring 2010 trenching program included the following

A total of 7 trenches with an aggregate length of 118 meters
were excavated along 250 meters of strike of the San Marcial
Structure. Trenches were oriented normal to the trend of the
structure. 77 Channel samples were cut from the trenches using a
handheld diamond saw with sample lengths varying from 0.90 to 2.20
meters in length.
The San Marcial project forms part of the Company's' newly
consolidated Rosario mining concession which totals 16,279 ha
(62.85 sq. miles). The concession includes the past producing
Plomosas and San Juan mines which were operated by Grupo Mexico
until 2001.
The San Marcial Project is situated in south eastern Sinaloa
State, along the western edge of the Sierra Madre Occidental
geological province. This linear belt of volcanic rocks,
approximately 1,500 km long by 250 km wide, is known to host many
important gold and silver producing mines and prospects. The
province is divided into two main Tertiary volcanic units referred
to as the Upper and Lower Volcanic groups, both of which are
separated unconformably by a period of erosion and associated with
local felsic intrusive activity. The contact between the two
volcanic groups is highly prospective for precious metal
mineralization, as a majority of the other known gold and silver
mines and prospects in the belt occur close to, if not just below,
the contact interval.
At San Marcial mineralization occurs along or adjacent to the
contact between the upper and lower volcanic groups in a zone of
faulting and brecciation varying from a few centimetres to over 10
meters in width over a strike length of at least 300 meters. The
structure is open to both the northwest and southeast. The breccia
is characterized by various amounts of silicification and
impregnated by minor blebs, thread, stringers and fine
disseminations of pyrite, sphalerite and galena. There is a marked
increase in silicification in zones of higher grade silver
mineralization. Weak sulphide mineralization persists into the
footwall below the lower silver rich structure. Overall sulphide
content is in the order of 3-5%.
All samples were sent to ALS Chemex Laboratories sample
preparation facility in Guadalajara Mexico with final analysis done
at their facilities in Vancouver, BC. Standard, blank, and
duplicate samples were inserted in every batch of 25 samples to
ensure laboratory QA-QC performance. Assaying for gold and silver
was by fire assay and other elements by four acid ICP-AES.
